Elon Musk wants to buy Twitter (TWTR) for $43 billion and take it private. The reason? To make the social network a free speech platform for the entire world. Essentially, Musk wants to stop Twitter from policing certain types of speech.

But, according to experts, removing Twitter’s checks on user-generated content could destroy the social network as we know it.

“If Twitter really had no rules, it would be a total cesspool,” Paul Barrett, deputy director of NYU Stern's Center for Business and Human Rights, told Yahoo Finance.

Musk initially took a 9.2% stake earlier this month, and was offered a board seat with the caveat that he couldn’t own more than 14.9% of Twitter. And while Musk initially accepted that offer, he just as quickly rejected it via, you guessed it, Twitter.

He is now attempting a hostile takeover by going directly to Twitter’s shareholders, in an effort to run the company, his favorite mouthpiece, as he sees fit. If he fails? Well, he said during a Ted Talk on Thursday that he’s got a plan B — though he didn’t elaborate on what that would entail.

"I'm not sure I'll be able to acquire it," Musk said during the chat.

But if the world's richest person truly allows all speech on the service, hate speech and misinformation would also flourish. And that would send users, and more importantly advertisers, fleeing for social networks that keep a tighter grip on speech.

Opening up Twitter would crush it

In a Wednesday filing with the Securities and Exchange Commission, Musk said he would purchase all of Twitter for $54.20 per share in cash. That equates to a 54% premium above the stock’s price before Musk took a major stake in the company, and a 38% premium over the platform’s share price the day before the SEC announced that 9.2% stake.

In his filing, Musk said that Twitter, “will neither thrive nor serve this societal imperative in its current form. Twitter needs to be transformed as a private company.”

How exactly he will do that remains to be seen, but the mercurial CEO of Tesla and SpaceX has previously spoken out against Twitter’s content moderation. But those guards on free speech appeal to many users and companies paying Twitter’s bills.

“The reason that the platforms do content moderation is not necessarily entirely because of their noble aspirations,” Barrett said. “It's because they have to do that to make the platform usable by normal people and attractive to advertisers.”

If Musk aims to improve Twitter and unlock its value, then he won’t achieve that goal by forcing users to post on the same platform as hate groups.
